A transdermal composition and method to be used as a treatment for plantar fasciitis is provided. Transdermal composition may include a combination of about 2% w/w to about 5% w/w of piroxicam and about 95% w/w to about 98% w/w of a natural permeation enhancement (NPE) composition. The NPE composition may increase the skin permeability, enhancing the transdermal delivery flux of piroxicam via a single transdermal application, thus, reducing the time of treatment. Transdermal composition may be applied upon an area of treatment, which may include myofascial trigger points linked to pain caused by plantar fasciitis, thus treating this condition more effectively. Moreover, employing a long acting NSAID such as piroxicam, in combination with the NPE composition, may act as a faster and effective treatment for an inflammatory process compared to typical treatments.
